3 Claims.

This invention relates to range-type oil burners and to igniting devices therefor. t

A range-type oil burner usually comprises a base which carries a pair of spaced perforated combustion tubes or cylinders and has al1-open top fuel channel which underlies the combustion space between said tubes.,v At the time of starting the burner in operation, the channel contains liquid oil-or other liquid combustible supplied through a control valve from a constant level oil chamber in which oil is maintained cornmonly from an inverted oil bottle. The oil in the channel is ignited, usually, rby introducing a burning igniter downwardly in the combustion space between the combustion tubes and into contact with the oil in the channel. Sometimes the channel contains a wick to facilitate the ignition of the oil.` In accordance with the present in-A-` vention the igniting device may comprise a Wire rod of suiiicient length `having a handle at one end and a porous mass of oil-saturated non-cornbustible material at the other end which is adapted to be ignited to ignite the oil in the burner. The porous material can contain a sub# stantial amount of oil and the flame cannot be blown outreadily afterit has served its purpose. Hence an object of the present invention is the provision of an vigniting device having a novel f flame-shutter incorporated vtherewith yand so ar-` ranged that, when desired, the snuffer can fall into position to enclose the ilainingmaterial and extinguish the flame. I s

Heretofore, no convenient-storage receptacle for the igniting device hasbeen proposed and hence it is a further object of kthe invention to provide such a receptacle in the form of a hollow supporting standard for the oil bottle or reservoir and in which standard the igniting device is adapted to be stored, with the snuing device having means for closing the opening in the standard and also for supporting the snufling device in a position on the igniting device where it can more or less automatically be held away from the oil saturated material at the time the igniting device is in use. v

A further object is generally to improve the construction of oil burners and igniting devices therefor.` Y

The oil burnerV associated with the present invention includes a burner base I0 having an open top fuel channel` I2 and supporting a pairr of concentric spaced perforated combustion tubes I4 and I6 onopposite sides of and upstanding above the top` yof the channel. Sometimes a wick I8 is disposed within the `channel I 2. `The burner is adapted to be contained within .the fire box of.

a coal range, not hereinshown. y At the time of starting the burner, oil ismadmitted into the fuel channel through a pipe 20 and a control valve 22 from a constant-level oil `chamber 24 to stand at some level in `the channel corresponding t0` the level of oil `inr the chamber. The chamber receives the `mouth of an inverted oil-containing bottle or reservoir 26 and thus maintains oil in the chamber, The chamber and bottle are sup-I ported on a vertical standard 28 which, in accord-` ance with the present invention, is hollow and open at the top, and is ,composed of a section ofpipeor tubing and is fixed to and supported at the bottom by feet 30. The igniting device for the oil in the ychannel-y I2 comprises a straight and'stiff small diameter metal rod- 32 of sufficient length to` extend from the top of the combustion tubes I4 `andlli through the space Vtherebetween and into contactwith the wick I8 or with the oil inthe channel.l The Y rod at its upper end is lprovided with a suitable handle herein sho-wn as a loop 34 formed at the end of the rod.v v A mass of porous oil-absorbent material 36, preferablynon-combustible, as fas-- bestos bres, is secured to the lower end of the rod and is adapted to absorb and retain a suitable amount of oil. The material can be charged with oil by immersing it in the oil in the chamber'24, after which the oil-saturated material can be ignited and inserted in the burner to ignite the oil therein. AfterI the burner has been vignited the flame of the igniting device should be extinguished.V It is diicult to blow out the iiame b-y reason of thel substantial amount of burning oil; and this manner of extinguishing. the ame is objectionable because of the odorv of the oil vapors. Hence the igniting device is provided with a snufng device which extinguishers the flame practically instantly and encloses and coolsand thus prevents the liberation of much objectionable odor. The snuiiing device 38 comprises essentially a plate 40 which has a passage 42 therethrough in which the rod 32 of the igniting device is slidable and which is held from detachment from said rod by the loop 34 at the upper' end and by the mass 36 of absorbent material at the lower end of the rod. A cylinder 44 is integral with said plate and depends therebelow and is concentric with the rod passage 42 and has a recess 46 therein which is closed by said plate 40 at the top and is open at the bottom. Said recess preferably is longer than said mass 36 of absorbent material and has a lateral dimension sufficient to receive and conne said material closely. Thus, when the snuifer is permitted to drop on the rod 32 the absorbent material passes into said recess and the flame is instantly extinguished, the oil also being cooled by the cool snuffer so that oil vapors arer not liberated.

Also in accordance with the present invention the snuf-Iing device is arranged to constitute a supportk for the igniting device'when not in use within the hollow standard 28. To this end, the plate 40 of the snufng device is circular and is large enough in diameter to overlie the open end of and rest upon the end of the standard and has a marginal depending rim or flange 48 within which the top of the standard is located and by which the plate is held against latera1 displacement. The igniting device thus is supported pendently within the standard by the snufling device, the ring 34 engaging the top of the plate 40 and said plate constituting `a closure for the openA top of said standard so as to prevent the escape of any odors that" may emanate from the saturated mass 36. The plate 40 also constitutes a holder for the snuing device at the time the igniting device is in use, the rim of the plate 40 and the handle 34 of the igniting device being grasped concurrently by the hand at the time the igniting device is being withdrawn from the standard and lighted and inserted in the burner, so that the snuiing'device is thus more or less automatically held at the top of the rod 82. After the burner has been lighted, the snumng device is released and falls over the flaming mass 36 and extinguishes the flame. f The igniting device is then restored to its position within the standard. s f l It will be apparent that, by the present inventionjI have provided a convenient igniter for oil burners, that is always at hand when needed and wherein any re hazard accompanying the `use andv storage of fthe device is eliminated.

Fig. 4 illustrates a modified form of snufilng device composed of stamped or pressed.` sheet metal parts, the plate 40a having a recess 50 in which the upper endvof a snufiing tube 44 is pressed and a rod-guide 42a being secured in an aperture in said plate.

Fig. illustrates a further modified form of the device wherein the snufling tube 52 has a reduced neck 54 that slidably receives the rod of the igniting device, the neck being fixed in a flanged opening of the plate 40bwhich,otherwise, has the same general construction and functions as the plate 40.
